• Security filtering discards any non-VoIP packets received on a port that are tagged with the voice VLAN ID. VoIP traffic
is identified by source MAC addresses configured in the Telephony OUI list, or through LLDP that discovers VoIP
devices attached to the switch. Packets received from non-VoIP sources are dropped.
• When enabled, be sure the MAC address ranges for VoIP devices are configured in the Telephony OUI list (voice vlan
mac-address).
